Jung Suk Won has recently been revealed as the 'hidden card' with secrets to his birth in the KBS drama, "Haeundae Lovers."

On the Tuesday episode, Choi Joon Hyuk, played by Jung Suk Won, and Go So Ra, played by Jo Yeo Jeong, finds out that they share the same mother. Near the end of the broadcast, Go So Ra finds a picture in Choi Joon Hyuk's wallet and she realizes that the woman in the picture is her biological mother and cannot hide her surprise. This comes after the episode set up the beginnings of a love triangle between the two and Lee Tae Sung, played by Kim Kang Woo, but the fact that Choi Joon Hyuk and Go So Ra may be brother and sister is another shock to the viewers. 

Jung Suk Won has portrayed other characters in other dramas like "Ojakgyo Family," where it turned out that he and another character were actually biological brothers. Jung Suk Won's management company said, "Only the author knows what happens to their relationship and what to do with this new secret and revelation. Jung Suk Won is putting a lot of effort into figuring out how best to portray the situations in a funny and sensical way."

Jung Suk Won currently portrays hotelier Choi Jun Hyuk in "Haeundae Lovers."
